a relnforced casing capable of further service.

more used casings it is obviously necessary to nest them together. It is difficult if not impossible to nest a casing within another in its usual commercial form owing to the relatively sm all diameter acrossthe c encherbeads. This f difliculty has been over'- come by cutting 0E one or both beads of a lcasing. It is also difficult to handle an annular body like a tire caslng and secure it together with any known fastening mechanism. This latter difficulty by supporting the tire casing around a fastening mechanism in a plane at right angles to a plane in which a needle or other suitable fastening implement is actuated and so that the force of lgravity acts upon the casing without substantial deformation ofits annular form. y

My invention has for its objects to provide suitable work-supporting mechanism in connection with thefastening mecha- In making a useful shoe from two oris overcome nism, preferably a sewing machine, forse-v curing together such casings.

To the attainment of these ends I sever a bead or beads from one or more casings, nest within it or them another casing osition4 the nested casings in the path of a astening mechanism, and secure the parts together. work I provide the horn or tubular arm of the machine with an. elevated. ortion shaped to permit the tire to be tilte transversely of the path of the needle, and in conjunction therewith, I makeL use of a -vertical standard in which slide two rods xed to and` supporting a vbracket or frame Garry- To support thev 'supporting means,

ing Vtwo friction rollers inclined to each other in the same plane. The vertical standard isplaced in line with the longitudinal axis of the horn to the'tright of the machine when viewed from theifront. The

'rods carrying the frame and sliding in the standard may be clamped in any adjusted position by, suitable. means such as two pivoted fingers engaged by a collar or washer on a screw-stud, which is provided with a handle for facilitatin advancement of the collar or lwasher to eect a binding engagement of the finger ends with the slide ro s. The invention also consists in certain details lof construction which will appear in the following description of the device illustrated inv the accompanying drawings, 1n which IFigure 1 is a view in perspective of a No. 98-3 Singer sewing machine and Fig. 2 is a detail of the adjusting mecha nism for a supporting frame looking down on the vertical standard.

The fastening mechanism, preferably a sewing machine, as shown in the drawin at 1, is provided with a rigid or fixed'wor supporting arm 2, usually known as a horn,

which contains a` lower thread mechanism that cooperates with the needle. Any suitable form of actuating mechanism may be employed to operate the needle and the` at this point being to permit a canting of the. internally supported annular casing aboutA the end of the horn as a pivot above or below thevplane of the tire when horizontal in order to locate the fastenings either close to the bead or well up on the sides of the shoe. In the `machine illustrated, the portion 3 is raised above the up er surface of the horn about 1% inches.

These sliderods may be clamped in any adjusted posi# tion by means of oppositely disposed L- shaped fingers 12 pivoted at 13 to the standard intermediate their ends in such fashion that one end 14 of a linger will bear against the rod and the other end 15 against a collar or washer '16 on a screw-stud 17 to which is securedv by a set-screw 18 a handle 19 for v facilitating advancement. of the collar or washer. The bracket or frame 7 may be of any suitable shape but as shown is cast in the form of a huge letter K and disposed at its ends are antifriction means for diminishing the drag imposed by the Weight of the casings upon the feeding mechanism which rotates the work. Preferably as shown the anti-friction means consist of roll-.

In the making of a reinforced tire casing a bead or beads is or are cut 'off from one or` 40 more used casings with any suitable implements or mechanism, the beadless casing or casings is or are then stretched over another casing having beads, and thus nested, the casings are placed in the path of a needle or other suitable mechanism for inserting fastenlngs. Preferably the nested casings are placed around the sewing machine being internally supported b the horn and externally supported by t e radially arranged i Nested casings sup- 1ported 1n this manner are as shown'rotatable y the feeding mechanism about an axis which passes approximately through the'u right standardof the sewing machine. It y be supported site side of the needle from thatshown or in various other locations. The preferred ar-V rangement is that shown in the drawings bey to readily handle the casings, lng point, and because it takes up a minimum ofloor space while utilizingthe force of gravity toloosely hold the tire imposithe lugs being so arranged that the.

casings may \in s, of

the machine is operated to stitch or other' tion illustrated in the drawings except as it' the terms of the claims.

may be restricted by osltioning the casings Theprinciple in is obviously availab e for use with a fasten-` mg mechanism placed on its side with the casings in a vertical plane or with the machine at an angle but the arrangement shown I deem preferable.

ile a sewing machine is shown and described it is obvious that any other suitable fastening mechanism could be used, but I deem a 'sewing machine to be preferable for the class of work mentioned.
